摘要：

本研究旨在明确缓释氮肥对江苏稻田的增产提效作用，为该地区水稻减肥增效提供理论依据。以水稻品种'南粳5718'为试验材料，设置普通尿素+普通尿素(T1)、普通复合肥+普通尿素(T2)、普通尿素+缓释尿素(T3)、缓释尿素+普通尿素(T4)、缓释尿素+缓释尿素(T5)共5个处理，研究不同氮肥品种配施对水稻产量、氮肥利用率及土壤理化性质的影响。结果表明：施用缓释氮肥能显著提升土壤全氮和碱解氮含量，促进水稻叶绿素含量和株高增加，提高作物产量和氮肥利用率。其中，底肥和追肥均施用缓释氮肥(T5)处理效果最优，水稻产量和氮肥利用率分别为9562.01 kg/hm2和45.48%，较普通尿素(T1)分别提高了25.1%和20.3%，较复合肥+普通尿素(T2)分别提高了23.3%和22.4%。研究表明缓释氮肥在江苏水稻生产中具有显著的增产提效潜力。

Abstract:

This study aims to clarify the yield-increasing and efficiency-improving effects of slow-release nitrogen fertilizer in rice fields of Jiangsu Province, providing theoretical basis for reducing fertilizer application while increasing rice production in this region. A total of five treatments with respective basal dressing and top dressing were set up in the study, including ordinary urea + ordinary urea (T1), ordinary compound fertilizer + ordinary urea (T2), ordinary urea + slow-release urea (T3), slow-release urea + ordinary urea (T4), and slow-release urea + slow-release urea (T5). We examined the effects of different treatments on soil physicochemical properties, rice yield, and fertilizer utilization efficiency, using 'Nanjing 5718' as the test variety. The results indicated that applying slow-release nitrogen fertilizer significantly increased the content of total N and alkali-hydrolyzable N in the soil and improved the chlorophyll content and plant height of rice, thereby improving crop yield and N fertilizer utilization efficiency. The optimal treatment was T5, which applied slow-release N fertilizer to both basal dressing and topdressing, contributing to rice yield of 9562.01 kg/hm2 and N fertilizer utilization efficiency of 45.48%. The values were 25.1% and 20.3% higher than those with only ordinary urea (T1), and 23.3% and 22.4% higher than those with compound fertilizer + ordinary urea (T2), respectively. All the results indicated that slow-release nitrogen fertilizer had significant yield-increasing and efficiency-improving potential in rice production in Jiangsu.

Key words: slow-release urea, soil physiochemical properties, rice yield, fertilizer use efficiency
